LCA (Life Cycle Assessment) - TX

From imde.io

Overview

Life Cycle Assessment (LCA) is a systematic methodology used to evaluate the environmental impacts associated with all the stages of a product's life, from raw material extraction through materials processing, manufacture, distribution, use, repair and maintenance, and disposal or recycling. LCA provides a comprehensive view of the environmental aspects and potential impacts of a product or service.

Objectives of LCA

  • Identify Improvement Opportunities: Pinpoint areas within the product life cycle where environmental impacts can be reduced.
  • Support Decision Making: Inform policymakers and industry leaders in making more environmentally conscious decisions.
  • Enhance Product Design: Aid in the development of more sustainable products by understanding their environmental footprints.
